Restic is a fast and secure backup program. In the following sections, we will

present typical workflows, starting with installing, preparing a new

repository, and making the first backup.

- ``--exclude-if-present`` Specified one or more times to exclude a folders content
|

if it contains a given file (optionally having a given header)
|
||||
|
||||
Basic example:
|
||||
Let's say we have a file called ``excludes.txt`` with the following content:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ cat exclude
|
||||
::
|
||||
# exclude go-files

*.go

# exclude foo/x/y/z/bar foo/x/bar foo/bar
|
||||
foo/**/bar
|
||||
$ restic -r /tmp/backup backup ~/work --exclude="*.c" --exclude-file=exclude
|
||||
|
||||
It can be used like this:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ restic -r /srv/restic-repo backup ~/work --exclude="*.c" --exclude-file=excludes.txt
|
||||
|
||||
This instruct restic to exclude files matching the following criteria:
|
||||
|
||||
* All files matching ``*.go`` (second line in ``excludes.txt``)
|
||||
* All files and sub-directories named ``bar`` which reside somewhere below a directory called ``foo`` (fourth line in ``excludes.txt``)
|
||||
* All files matching ``*.c`` (parameter ``--exclude``)
|
||||
|
||||
Please see ``restic help backup`` for more specific information about each exclude option.
|
||||
|
||||
Patterns use `filepath.Glob <https://golang.org/pkg/path/filepath/#Glob>`__ internally,
|
||||
see `filepath.Match <https://golang.org/pkg/path/filepath/#Match>`__ for syntax.
|
||||
Patterns are tested against the full path of a file/dir to be saved, not only
|
||||
against the relative path below the argument given to restic backup.
|
||||
Patterns need to match on complete path components. (``foo`` matches
|
||||
``/dir1/foo/dir2/file`` and ``/dir/foo`` but does not match ``/dir/foobar`` or
|
||||
``barfoo``.) A trailing ``/`` is ignored. A leading ``/`` anchors the
|
||||
pattern at the root directory. (``/bin`` matches ``/bin/bash`` but does not
|
||||
match ``/usr/bin/restic``.) Regular wildcards cannot be used to match over the
|
||||
directory separator ``/``. (``b*ash`` matches ``/bin/bash`` but does not match
|
||||
``/bin/ash``.) However ``**`` matches arbitrary subdirectories. (``foo/**/bar``
|
||||
matches ``/dir1/foo/dir2/bar/file``, ``/foo/bar/file`` and ``/tmp/foo/bar``.)

||||
Environment-variables in exclude-files are expanded with

see `filepath.Match <https://golang.org/pkg/path/filepath/#Match>`__ for

even if restic is passed a relative path to save. Environment-variables in
|
||||
exclude-files are expanded with `os.ExpandEnv <https://golang.org/pkg/os/#ExpandEnv>`__.
|
||||
|
||||
Patterns need to match on complete path components. For example, the pattern ``foo``:
|
||||
|
||||
* matches ``/dir1/foo/dir2/file`` and ``/dir/foo``
|
||||
* does not match ``/dir/foobar`` or ``barfoo``
|
||||
|
||||
A trailing ``/`` is ignored, a leading ``/`` anchors the
|

pattern at the root directory. This means, ``/bin`` matches ``/bin/bash`` but

does not match ``/usr/bin/restic``.

|
||||
Regular wildcards cannot be used to match over the
|
||||
directory separator ``/``. For example: ``b*ash`` matches ``/bin/bash`` but does not match
|
||||
``/bin/ash``.
|
||||
|
||||
For this, the special wildcard ``**`` can be used to match arbitrary
|
||||
sub-directories: The pattern ``foo/**/bar`` matches:
|
||||
|
||||
* ``/dir1/foo/dir2/bar/file``
|

* ``/foo/bar/file``
|

* ``/tmp/foo/bar``

Local Cache
|
||||
===========
|
||||

In order to speed up certain operations, restic manages a local cache of data.

This document describes the data structures for the local cache with version 1.

||||
Versions
|
||||
--------
|
||||
|
||||
The cache directory is selected according to the `XDG base dir specification
|
||||
<http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html>`__.
|
||||
Each repository has its own cache sub-directory, consting of the repository ID
|
||||
which is chosen at ``init``. All cache directories for different repos are
|
||||
independent of each other.
|
||||
|
||||
The cache dir for a repo contains a file named ``version``, which contains a
|
||||
single ASCII integer line that stands for the current version of the cache. If
|
||||
a lower version number is found the cache is recreated with the current
|
||||
version. If a higher version number is found the cache is ignored and left as
|
||||
is.

||||

||||
Snapshots, Data and Indexes

|
||||
